I PHONOGRAPH.

Application filed June 30, 1922. Serial No. 571,993.

To all whom it may concern.

Be it known that I, SEVERIN J. Roam n a citizen of the United States,and resident of Lewistown, in the county of Fergus and State of Montana,have invented certain new and useful Improvements in Phonographs, ofwhich the following is a specification.

This invention relates to phonographs and the subject matter of thisapplication is disclosed in my -United States Patent #1,420,668. 7

In the phonographs now in general use the tone is usually subdued byclosing the shutters which extend across the horn and these shutterswhen in their open position greatly detract from the clearness of thereproduced tones, and it is therefore, an important object of thisinvention to provide novel means whereby the tones may be subduedwithout the employment of these shutters.

By the use of the improved phonograph the effect of distance is given tothe reproduced tones and a softer and more pleasing tone is provided,all of which adds to the desirability of the phonograph.

Further the invention forming the sub ject matter of this applicationaims to provide novel'means whereby the auxiliary horn may be readilyand conveniently attached to the phonograph. 1

A further Object isto provide a phonograph which is of highly simplifiedconstruction, neat in appearance and cheap to manufacture. r

Other objects and advantages will be apparent during the course of thefollowing description. I I I In the accompanying drawing forming a partof this application and in whichlike numerals are employed to designatelike parts throughoutthe same,

Figure 1 is a perspective of a phonograph constructed in accordance withthis invention, parts being broken away to illustrate the auxiliaryhorn,

Figure 2 is a detail sectional view through the phonograph, the viewillustrating the means employed to attach the auxiliary horn.

Figure 3 is a perspective of an attaching member embodied in theinvention.

In the drawing wherein for the purpose of illustration is shown apreferred embodiment of the invention, the numeral 5 designates thecasing of a phonograph, while the numeral 6 designates a concealed horn,the

sides of which are arranged at the side walls of the casing or cabinet.I

Figure 1 illustrates that a combined sound board and closure 7 is hingedat its rear edge as indicated at 8 to the rear side of the concealedhorn 6 and the sound board forms a convenient means whereby the volnineof the sound from the concealed horn 6 may be regulated.

As in the case of the aforesaid.application, the sound board 7 hasconnection with a plurality of flexible elements 10 trained aboutpulleys 11 mounted on a shaft '12.. The shaft 12 extends transverselythrough the cabinet and is formed at one end by a crank 13 by means ofwhich the pulley 11 may be rotated for raising or lowering the soundboard 7. a

Figure 1 further illustrates that the phonograph is provided with a tonearm 16 which has communication with the concealed horn 6 and conductsthe reproduced sounds to the horn.

A coupling member 20 is mounted between the tone arm 16 and theconcealed horn 6 and is provided with a valve 22. IVhen the valve 22 isin the position illustrated in dotted lines in Figure2 the sound wavesdo 8 not travel through the concealed horn but. enter the upperattaching section 26 of an auxiliary horn generally described by thenumeral 27 ()u the other hand when the valve 22 is in itsfull lineposition as illustrated in Figure 2 the sound waves are conduct dthrough the concealed horn.

In carrying out the invention the shaft or pivot element 23 is extendedout through one side of the cabinet and is provided with an actuatingmember or pointer 30 which may be manually turned for positioning thevalve 22 as desired. As illustrated in Figure 1, one side of the cabinetis provided witha dial 33 over which the pointer 30 plays and it will beseen that the dial and the pointer form a convenient means foraccurately indicating the position of the valve 22.

Considering Figures 1 and 2 it will be observed that the auxiliary horn27 arranged in the rear of the horn 6 has its lower end flared andprovided with an outlet box 38 extended through the back of thephonograph and having its exposed side apertured as indicated at 40 forthe disc g f t e. t ne Waves.

In operation if it is desired to produce a soft mellow tone having theeffect of dis tance the sound Waves are directed to the long narrowauxiliary horn 27 and the tone waves are discharged through the apertures 40. The tones thus discharged through the apertures 40 are more orless free from the shrilled or high notes and the tones are free fromother defects highly noticeable in the ordinary phonograph. Specificallythe scratching sounds so noticeable in the phonographs now in use arealmost entirely eliminated.

The clearer reproduction of the sounds is generally accounted for by thefact that the sound is not choked off at the tone arm or by means of theshutters ordinarily employed. K I

With reference to the foregoing description taken in view ofthevaccompanying drawing it will be apparent that a phonographconstructed in accordance with this invention does not differ radicallyin ap pearance from the phonograph nowin the market, and therefore theinvention will not be prejudiced when placed upon the market. I

The improved auxiliary horn consists of an upper section 26 and a lowersection {4 jointed to the uppe r section by means of a couplingmemher46. The tone arm may be readily connected to the valve casing 20by means of a U-shapedattaching member 50 preferably formed from springmetal. The spaced parallel side arms of the Ushaped attaching member arearranged on opposite sides of the auxiliary horn and the casing 20 andare formed with notches which partially receive attaching pins 56:carried by the casing. The forward portions of'the arms of theU-shaped'member 50 have their upper sides formed with notches 5:7.rtopartially receive attaching pins or lugs 58- ar ranged below and inadvance of the lugs 58.

In attaching the auxiliary horn to the casing 20 the bight portion ofthe U-shaped member- 50 is engaged with a rear side of the horn and isreceived within a notch 60. carried by an attaching bracket 61.. Thearms of the U-shaped member are now are ranged on opposite sides of thecasing: and are engaged with lugs 56 and. 58 in the manner illustratedin Figure 2 so that the resiliency inherent in the U-shaped member willforce the horn flatly into contact with the open side of the casing soas to positively prevent the escape of sound Waves, a gasket 63 islocated between the casing 20 and the auxiliary horn.

By the use of this invention the tone may be readily and convenientlyvaried according to the desire of the operator by simply rotating thepointer 30 over the dial and as previously stated tones of a verysuperior quality are reproduced.

It is to be understood that thefiorm of the invention herewith shown anddescribed is to be taken as a preferred sample of the same and that suchnovel changes in arrangement and description of parts may be made aswill remain within the spirit of the invention and the scope of what isclaimed.

1. A phonograph having a sound conduit forming part of a sound passageand being provided with a lateral opening, a hornhav ing an attachingsection provided with a corresponding opening, and means for holding'the section in place upon the conduit when the openings are inregistration, said means including pins carried by the conduit, a Ushaped member extending around said section to the sides of-the conduitand having opp'ositely' disposed notches to engage the pins, and therebyretain its posi: tion, and means including a bracket carried by thesection beneath which'said member engages. w v v 2. A phonograph havinga conduit forming part of a sound passage and being pro vided with alateral opening, a horn having an attaching section to. be fittedagainst the conduit and having a corresponding opening, resilient meansbent to embrace the attaching section and extend along the sides of theconduit, saidme'ans having oppositely positioned notches, pins carriedby the conduits to engage said means on opposite sides and in thenotches, and means on the attaching section beneath which a portion ofsaid bent means is positioned to aid in supporting the attaching sectioninplace.
